7.1
Maintenance
Note:
If increased running noises occur after several 100 operating hours, relubrication may be
necessary. Contact HIWIN GmbH for this purpose.
The ball or crossed roller bearings installed in the rotary tables require an adequate supply of
lubricant, just like any rolling bearing. The lubricants reduce wear, protect against dirt, protect
from corrosion and lengthen service life.
The crossed roller bearings used in the rotary tables are equipped with seals that prevent the
lubricant from escaping from the bearing.
After the rolling bearings have been mounted, an initial greasing is carried out at the factory.
If the rotary table does not heat up disproportionately during operation (higher than 50 °C) and
does not require high speeds (higher than 500 rpm), relubrication is normally not necessary.
